No Parking Lights in Rear and no Blinkers?

[kristopherdb]

Ill give that a look this week, tonight after work is supposed to be hot so I will be hiding from the sun!

Meanwhile we're getting ready for winter over here...

[Gary Lewis]

It'll be 93 degrees here on Saturday for the show. What's winter?  😳

[kristopherdb]

ok I got a tester finally and took care of the trailer mess in the back still no lights and I am not getting any power to the blower and or turn signal fuses. Could this be because my wiper switch is disconnected? I followed the wiring diagram as suggested and I have never read one before so bare with me, I have no parking lights, no license plate lights, no backup lights, no turn signals, and no power to those two fuses. If I touch the center pin on the parking bulb I get a ground tone. That tells me I am getting ground to the power somehow right?

[Gary Lewis]

Kristopher - We are going to have to divide and conquer these problems.  Let's do the power to the fuses first - you don't have power to Fuse 5, which is the Turn/Stop/Hazard one, nor Fuse 9, which is the A/C-Heat fuse.  Right?

From the drawing on Page 13 of the 1981 EVTM those two fuses, and only those fuses, are fed by the gray/yellow (GY/Y) wire from the ignition switch, with nothing in between.  So, you need to confirm if that wire has power on it when the key is in Run.  If not, and assuming the big Yellow wires feeding the switch are hot at all times, then your ignition switch has a problem.

Here's the schematic from Page 13 with some markups:

now I am second guessing myself, I had reached under the column to turn the key on and it does have a habit of sticking in start instead of run. I usually notice because my gas says Empty, bump the key back and all is well. I should probably make sure I was not in start before I go any further.

Good plan, Stan.

We can pick up from there once you report back.

[PetesPonies]

And do you reliaze how these Ford switches are designed? The actual switch is not where the key is inserted.

[Gary Lewis]

As explained here: http://www.garysgaragemahal.com/ignition-switch.html. A full-service website. 😉

What happens many times with these switches, is the two halves of the diecast  metal, start to separate . . . . . causing all kinds of interesting possibilities . . one bad one being fire  :(

[kristopherdb]

Ok I put in a new wiper switch and bam 99% of my lights are back to normal. I had pulled two from the junkyard today thank god. The first had the same pins and a ground wire but didn’t work. It seemed like it had delay built in maybe, I was hopeful at least. The other switch got me back in business.

Glad you got it working!  But you said 99%. Dare I ask what isn't working?

[kristopherdb]

License plate light and one reverse light.

That EVTM will be a big help. You can see the same thing on here, but there's nothing like having something to carry with you when working on the truck. 👍

As for the last two lights, I'm guessing it is the bulbs. Obviously you have power back there or the other backup light and license tag light wouldn't work. So it could be wiring, bulb, or ground. Try the bulbs first.

Interesting thread

Out of curiosity, why Did a New wiper switch help on Parking lights?
